Recommendation Guidelines and Practices for the Design and Validation of EHA Thermal Management Considerations, particularly for Low Temperature Operation.

Recommendations for EHA Pump and Motor sizing based on considerations for various actuator performance requirements, including no-load speed, breakout torque, low temperature, stiffness, dynamic response, maximum pressure-velocity capability, and other conditions.

This SAE Aerospace Information Report (AIR) has been compiled to provide information on: a. The particularities of EHAs and their derivatives that make their implementation useful to meet some specific system requirements, solve some system architecture issues, or provide system optimization within the flight control actuation and hydraulic generation/distribution perimeter. b. System architecture drivers and basic schematics, actuator principle schematics, and basic characteristics, for various civil and military aircraft.

This SAE Aerospace Recommended Practice (ARP) provides guidelines for the creation of specifications for the Motor Control Electronics (MCE) that are used for operating electrically powered actuators including: Electromechanical Actuators (EMAs) Electrohydrostatic Actuators (EHAs) Electric Back-Up Hydraulic Actuators (EBHAs)

This Aerospace Recommended Practice (ARP) provides recommended test requirements for Electrohydrostatic Actuators. NOTE: This document does not address tests and issues of a higher system level, such as the primary flight control surface level where multiple EHAs and or EHSAs may be integrated.
